Which regulatory body oversees workplace safety in the United States?

The Occupational Safety and Health Administration (OSHA) is the regulatory body specifically focused on workplace safety in the United States. Established in 1970, OSHA is tasked with ensuring safe and healthy working conditions by setting and enforcing standards, as well as providing training, outreach, education, and assistance. This organization plays a crucial role in reducing workplace hazards and preventing work-related injuries and illnesses.

OSHA's regulations cover a wide range of workplaces across various industries, including construction, manufacturing, and healthcare, making it an essential entity for ironworkers and others involved in high-risk jobs. By overseeing compliance with safety standards, OSHA helps to ensure that employers provide a safe working environment for their employees.

The other options, while important in their respective areas, do not focus exclusively on workplace safety. The Department of Labor oversees broader labor issues, including wages and unemployment, but does not specifically enforce workplace safety regulations. The Environmental Protection Agency (EPA) deals primarily with environmental protection and regulation, focusing on air and water quality rather than workplace safety. The Federal Emergency Management Agency (FEMA) is responsible for disaster response and recovery rather than everyday workplace safety. Thus, OSHA stands out as the correct answer regarding the oversight of workplace safety in the United States.
